BOILER AND WATER-H EATER.

SPECIFICATION forming part of Letters Patent No. 261,076, dated July 11, 1882.

Application filed February 24, 1882. (No model.)

.To all whom tt may concern:

Be it known that I, WILLIS L. BRowNELL, of Brooklyn, in Kings county, and State of New York, have invented a certain new and useful Improvement in Boilers or Water-Heaters, of

which the following is a specification.

This improvement relates particularly to the water-boilers or heaters which are used in conjunction with ranges in houses.

1o The object of theimprovement is to provide for more effectively securing a head or bottom or end in place.

To this end theimprovement consists in the combination, with the body of a boiler or waterheater, of a head or end having an outwardlyturned ilange inserted into said body, an independent ring inserted within and bearing directly upon said liange, and having its outer edge coincident, or nearly coincident,with the zo end of the body, and means for clamping said ring and body against opposite sides of said ange. l

It also consists in the combination, with the body of a boiler or water-heater and a head 2 5 having an outwardly-turned flange, of an independent ring fitting within said ilange, all being disposed as particularly hereinafter described and claimed, so as to form an annular space for solder or molten metal, wherebya 3o very tightjoint may be produced.

Preferably thebody of the boiler or waterheater, the head, and the independent ring will be copper-lined, to facilitate making a good soldered joint between them.

In the accompanying drawings, Figure lis a central vertical section of a boiler or waterheater embodying my improvement. Fig. 2 is a vertical section on a larger scale, illustrative of the joint between the body and an end; and

4o Fig. 3, a vertical section on` the same scale, illustrative of a modified form of joint between the body and an end.

Similar letters of reference designate corresponding parts in all the figures.

A designates the body of a boiler or waterheater. It may be made of cylindric form, and of cast or sheet iron or other suitable material. As shown, it has a lining of copper, and this lining may consist ofa sheet of copper, C,prop

erly disposed within and fitted to the body. 5o

D designates the head or upper end, which is made dome-shaped, as usual, in this example ofmy invention. As here shown, it is provided with a lining, E, which may consist ofa sheet of copper. A ring of sheet-copper may advantageously-be arranged between the bodylining C and the head D; or the head-lining may be bent around the edges ofthe head, as shown at F, thereby in effect forming such a ring. Rivets b, passing through the head-lin- 6o ing E, the head D, the ring F, the body-lining C, and the body A, secure the several parts together. Y

G designates the bottom head or lower end of the boiler or water-heater. It is provided with a downwardly or outwardly extending ange, a, and has applied to its interior a lining of copper, H, which may be used in the form ota sheet, and preferbl y extends between the flange a and the bodylining C. As shown 7o in Figs. l and 2, the ange a and liningl H do not extend down to the bottom edge of the body A; but in the example of my invention shown in Fig. 3 they are made much deeper and extend to the lower edge of the body. I designates a ring, which may be of cast or sheet iron or other suitable material. It fits within the flange a of the bottom G, and preferably has a ring, J, of copper, interposed between it and the body-lining C. This ring 8o J may be of sheet-copper. Rivets c, passing through the ring I, ring J, bodylining O, and body A, secure the several parts together. In the form of myinvention shown in Figs. 1 and 2 these rivets do not pass through the iange 85 a, of the bottom head, G; but in the example of my invention shown in Fig. 3 they' pass th-rough this flange and the bottom lining, H, as well'as through the other parts named. In the example of my invention shown in Figs. l 9o and 2, solder K will preferably be introduced in the annular space which is left between the ring I or the ring J, when the latter is used, and the body A'or the body-lining C, when this isemployed,andagainsttheedgeoftheangea. The copper body-lining O and the ring J, of

1 the parts to which they are respectively applied.

In lieu ot' solder, molten metal, preferably lead or zinc, may be used to fill the annular space left between the ring I or its liningring J, when the latter is used, in the example of my invention shown in Figs. 1 and 2.

The rivets c may be inserted and fastened after the solder or molten metal is in place, if desirable; or they may in some cases be entirely omitted in the form of my invention which is illustrated in Figs. l and 2.

In order to stay or brace the bottom head, G, against an upward thrust or blow when the rivets c do not pass through it, a ring may be fastened in place above the bottom to form an abutment for it; or rivets d, passing through the body A, or the body A and the body-lining C, may be employed to form an abutment for this purpose.

By my improvement I form a very strong and tight joint at a moderate cost, and with a less number of rivets than are ordinarily employed. Moreover, I avoid much expense of thelabor which is ordinarilyexpended in chipping and calking.

A head secured in place according to my invention can be removed and replaced at much less expense than a bottom secured in the ordinary manner, and with much less danger of entailing damage to the component parts of the boiler or water-heater.

By the use of the independent ring I, great strength is imparted to the boiler or waterheater in direction transverse to its axis. It is preferable to providing the bottoni with integral double flanges, because when either liange or the bottom itself becomes damaged all are rendered useless, whereas the independent ring can be used with a new bottom. Moreover, the doubleintegral flanges produce a projection on the outside of the boiler or water-heater, which is obviated by my invention. It is obvious that thejoint can be made with greater facility with the use ofthe ring I than where a bottom having double integral flangesis used.

The top head or upper end may be secured in place like the bottom or lower-end, if desirable.

I provide the ends with the usual sockets, ej', for the attachment ot' the water-pipes.

What I claim as my invention, and desire to secure by Letters Patent, isi 1. Ihe combination, with thc bodyof a boiler or water-heater, of a head or end having an outwardly -turned flange inserted into said body, an independent ring inserted within and bearing directly upon said flange, and having its outer edge coincident, or nearly coincident, with the end ofthe body, and means for clamping said ring and body against opposite sides of said flange, substantially as speciiied.

2. The combination, with the body ofaboiler or heater, of a head havin g an outwardly-turned liange inserted into said body, so that the body extends beyond theV edge of the flange, and an Y independent ring inserted within the ilange and projecting outward beyond the edge thereof, whereby an annular space for solder or molten metal is formed between said body and ring beyond the edge of the flange, substantially as specified.

3. rlhe combination, with the head G, provided with the iiange a, of the body A and ring I, bearing against opposite sides of the flange and projecting beyond the same, and the solder or metal K, introduced between the body and ring and against the edge of the iange, substantially as specified.

4. The combination ot' the body A, the head G, provided with the flange a, the ring I, the solder or metal K, and the rivets or bolts inserted through said body and ring, and also passing through the solder or metal K, substantially as specilied.

5. The combination, in a boiler or water-l lieater, of a body ot' iron or analogous metal, a copper lining therefor, a head ot' iron or analogous metal having an outwardly-extending tlange, a copper lining or linings covering the head and the interior and exterior of the flange, an independent ring of iron or ICO analogous metal extending beyond the edge of the flange, and solder or molten metal introduced between the ring and the lining of the body and beyond the edge of the ange, substantially as specified.

6. The combination,in a boiler or water-heater, of a body of iron or analogous metal, a copper lining therefor, a head of iron or analogous metal having an outwardly-extending flange, a copper lining or linings for said head and the interior and exterior ot' said flange, an independent ring of iron or analogous metal inserted within said flange, and a ring of copper covering the same, both said rings extending beyond the edge of said iange, and solder or molten metal introduced between the rings and body-lining and beyond the edge ot' said flange, substantially as specitied.
